Re: EUDI Wallet Consortium (EWC)

Hi Michael, I think it’s just what happens when one product tries to
fulfill too many different use cases. To me, it’s the reason why the App
Store exists despite Apple’s product excellence on the base OS + hardware,
and why people like to run 3rd party programs on Windows.

Could there be a super OS-like wallet that has its own apps on top? Maybe
from a market leader with existing network effects or new entrant that can
accumulate them quickly, but I think each layer of nesting detracts further
from potential UX. Also I like the idea of getting away from walled gardens
as an ecosystem, and for those network effects to accumulate to open
protocols instead.
